When people recognize something they pay more attention to it. We can use this when creating learning material to increase learner engagement which can help to improve the learning outcome. A simple way to do this is to use real scenes from work when creating learning material. The picture above is from the canteen at work with two characters from Articulates software inserted.
People will instantly recognize the canteen and I believe (without any scientific basis) pay more attention to the content than they would if it was a generic scene.
